I'm looking for a good survival game for the PC?

They don't need to have enemies like zombies or wild animals, but I'm not against that either. I prefer ones that seem kind of like a simulation (meaning you have to eat, drink and maybe sleep to survive). I've played WarZ and loved it, but I don't very much like the mmo part. I mainly enjoyed that loot/equip system where they are specific slots for items or ones where you have to rearrange items in your bag to make them fit. It reminded me of RPG games I played as a kid and made it feel more "real" so to speak. Graphics are not a big issue with me, but I would prefer them to be decent enough (NOT Fallout 1 and 2 graphics). The one's I've played that I can think of are listed below, so refrain from posting those. Thank you in advance.

The full Fallout series since one
Infestation Survivor Stories (The WarZ)
7 Days to Die
All of the Elder Scrolls since Daggerfall
Farcry trilogy
Minecraft
Miasmata
Fallen Earth
Arma 3 (if you could count that)

That's all I can think of for now.

Added (1). Another thing, it doesn't have to have a story. I'm fine with being thrown into a world and told to just survive.

Added (2). I should also add, co-op is always good. Meaning, I can invite someone to join my server or my game privately without the worry of it being filled to the brim with griefers.

You could try Rust. Here is a summary from steam.
The only aim in Rust is to survive. To do this you will need to overcome struggles such as hunger, thirst and cold. Build a fire. Build a shelter. Kill animals for meat. Protect yourself from other players. Create alliances with other players and together form a town. Whatever it takes to survive.
And here is the link with a trailer.

Skyrim and gta 5 are good games. They are so fun, awesome RPG and open world. I would recommend getting skyrim

Try Don't Starve on Steam. It's a survival game similar to Minecraft but in 3rd person.

Walking Dead(not so much survival simulation, but still fun and fits what you're looking for)
Rust (laid back, multiplayer survival game on steam)
DayZ(multiplayer survival game on steam)

Survival Horror Games
